    OPINION
    LUTTIG, Circuit Judge:
    Law enforcement officials literally risk their lives each time they
    approach occupied vehicles during the course of investigative
    traffic
    stops. As the Supreme Court has repeatedly observed,"a significant
    percentage of murders of police officers occurs when officers are
    making traffic stops." United States v. Robinson, 
    414 U.S. 218
    , 234
    n.5 (1973). In recognition of the extraordinary dangers to which
    offi-
    cers are exposed during such encounters, the Court has consistently
    accorded officers wide latitude to protect their safety,
    authorizing
    them, inter alia, to routinely order both drivers and passengers to
    exit
    their vehicles during such stops and to conduct the equivalent of
    "frisks" of automobile interiors whenever they reasonably believe
    their safety might be in jeopardy.
    The advent of tinted automobile windows, however, has threatened
    to bring to naught these essential law enforcement protections.
    Con-
    fronted with the grave risk that tinted windows pose to the safety
    of
    law enforcement personnel, we address herein whether the govern-
    ment's substantial interest in officer safety during a lawful
    traffic stop
    outweighs the intrusion on the privacy interests of the vehicle's
    occu-
    pants which results when, because of heavily tinted windows that
    pre-
    vent the interior compartment from being viewed, an officer opens
    a
    door of the vehicle in order to ensure that the vehicle's driver is
    unarmed and that there are no other occupants who might threaten
    his
    safety during the investigatory stop. We conclude that, perhaps
    gener-
    ally, but at least under the circumstances of this case, the
    substantial
    government interest in officer safety which exists when law
    enforce-
    ment officers must approach vehicles with heavily tinted windows
    far
    outweighs any minimal privacy interest the suspect retains in the
    oth-
    erwise visible interior compartment of his vehicle.
    I.
    At approximately 9:00 a.m. on the morning of April 29, 1996, three
    officers from the Baltimore City Police Department-- Officers
    Mackel, Buie and Hamel -- were patrolling a high crime area in West
    Baltimore known for its open narcotics trafficking when they saw a
    2
    late model, black Nissan Pathfinder with heavily tinted windows
    ille-
    gally parked in the middle of the street, effectively blocking
    traffic.
    See Md. Transportation Code Ann. §§ 21-1003(r), 27-101(a) & (b)
    (Michie 1996). The officers, who were armed and wearing bullet-
    proof vests over their uniforms because of the dangerousness of
    their
    assignment, see United States v. Stanfield, 
    906 F. Supp. 300
    , 301
    (D.
    Md. 1995), circled the block and, when the driver of the Pathfinder
    made no effort to move his vehicle to allow a free flow of traffic,
    parked their unmarked vehicle in front of the Pathfinder. Upon
    exiting
    their cruiser, the officers noticed that the Pathfinder's driver,
    appel-
    lant Billy Howard Stanfield, was talking to a man leaning from a
    sec-
    ond story window, whom the officers recognized as William Staten,
    a known drug dealer. See id.; J.A. at 151-52 (testimony of Officer
    Mackel); see also J.A. at 19 (Government's Memorandum of Law in
    Response to Defendant's Motion to Suppress Evidence).
    The officers approached Stanfield's Pathfinder from both the driver
    and passenger sides, and, as they did so, they noticed that the
    front
    driver's side window was down, but that the front passenger side
    win-
    dow was raised. See 
    Stanfield, 906 F. Supp. at 301
    , 303. The
    tinting
    on the Pathfinder's windows was so dark that Officer Mackel, who
    was approaching on the passenger's side, could not see into the
    vehi-
    cle. See 
    id. at 302,
    303. Nor could Officers Buie and Hamel see
    much
    of the vehicle's interior during their approach from the driver's
    side.
    As a consequence of the officers' inability to see inside the
    vehicle
    as they approached, Officer Mackel opened the front passenger side
    door of Stanfield's vehicle in order to determine whether Stanfield
    was armed or had access to weapons and whether he was alone in the
    Pathfinder. When Officer Mackel opened the passenger door, he saw
    in plain view, from his vantage point entirely outside the vehicle,
    see
    
    id., a clear
    plastic bag of cocaine protruding from the mouth of a
    brown paper bag which was overturned on the back seat of the Path-
    finder. See 
    id. & n.6.1
    The officers arrested Stanfield, searched
    the
    _________________________________________________________________
    1 The recited facts are those as found by the district court. A
    number
    of the material facts were vigorously disputed at the suppression
    hearing
    and, ultimately, the district court did not fully credit the
    testimony of
    either the officers or Stanfield, a fact which brings the case to
    us in a
    somewhat awkward posture. For example, the officers testified that
    both
    the front driver and passenger side windows were open, and that the
    3
    Pathfinder, and discovered a nine-millimeter semi-automatic hand-
    gun, numerous empty vials, two contact pagers, and over 200 grams
    of cocaine. See 
    id. at 302.
    Stanfield was subsequently charged with
    possession with intent to distribute cocaine and possession with
    intent
    to distribute cocaine base in violation of 21 U.S.C.§ 841(a)(1).
    Prior to trial, Stanfield moved to suppress the cocaine seized from
    the back seat of his Pathfinder, contending that the search
    affected by
    Officer Mackel's opening of the front passenger door was
    unconstitu-
    tional under the Fourth Amendment and, therefore, that the cocaine
    discovered as a consequence of that search must be suppressed. Fol-
    lowing an evidentiary hearing, the district court denied the
    motion,
    upholding the search on two independent grounds. First, citing
    Texas
    v. Brown, 
    460 U.S. 730
    , 740 (1983), the district court held that
    Offi-
    cer Mackel's opening of the passenger side door was permissible
    because Stanfield did not have a legitimate expectation of privacy
    in
    the interior of his car. See 
    Stanfield, 906 F. Supp. at 304
    n.9.
    Second,
    the district court held that, under Michigan v. Long, 
    463 U.S. 1032
    (1983), "Officer Mackel was Constitutionally permitted to open the
    door to determine whether there were other[ ] [occupants in the
    vehi-
    cle] and if any weapons were within Stanfield's immediate reach,"
    determinations which the district court found were otherwise
    virtually
    impossible because of the heavy window tinting. Stanfield, 906 F.
    Supp. at 304; see also 
    id. at 303-04
    & n.11 ("[B]ecause Officer
    Mackel was unable to see through the heavily tinted windows of the
    _________________________________________________________________
    cocaine was seen through the open passenger window. See 
    Stanfield, 906 F. Supp. at 301
    . The district court, for reasons we find difficult
    to under-
    stand, rejected this testimony seemingly for the reason alone that
    it was
    fifty-nine degrees on the day in question, and therefore "it
    seem[ed]
    more likely than not that [Stanfield] would have left the
    passenger's side
    window up." See 
    id. at 303
    n.5. Stanfield, for his part, testified
    that the
    passenger side window was raised and that Officer Mackel opened the
    passenger side door, climbed inside the vehicle, and searched under
    the
    back seat to find the cocaine. See 
    id. at 302.
    The district court
    specifi-
    cally found, however, that the cocaine was in plain view once
    Officer
    Mackel opened the passenger side door and that Officer Mackel,
    contrary
    to Stanfield's contention, neither entered the vehicle nor searched
    under
    the vehicle's seat. See 
    id. at 303
    n.6.
    4
    Pathfinder, he had an objectively reasonable belief that Stanfield
    (or
    a hidden passenger) was potentially dangerous.").
    Following the district court's denial of Stanfield's suppression
    motion, Stanfield pled guilty to one count of possession, reserving
    the
    right to appeal the district court's suppression ruling that is now
    before us. For the reasons that follow, we affirm.
    II.
    "[T]he ``touchstone of the Fourth Amendment is reasonableness.'"
    Ohio v. Robinette, 
    117 S. Ct. 417
    , 421 (1996) (quoting Florida v.
    Jimeno, 
    500 U.S. 248
    , 250 (1991)). And, as the Court explained in
    Pennsylvania v. Mimms, 
    434 U.S. 106
    (1977), reasonableness "de-
    pends ``on a balance between the public interest and the
    individual's
    right to personal security free from arbitrary interference by law
    offi-
    cers.'" 
    Id. at 109
    (quoting United States v. Brignoni-Ponce, 
    422 U.S. 873
    , 878 (1975)). Under this balancing test, the Supreme Court has
    consistently approved of protective searches of persons, vehicles,
    and
    even homes, during routine and other lawful investigatory
    detentions,
    in recognition of the paramount interest in officer safety and the
    extraordinary risks to which law enforcement officials are exposed
    during such detentions.
    Thus, for example, in Terry v. Ohio, 
    392 U.S. 1
    (1968), the Court
    sanctioned the now-familiar "pat-down" search, or "frisk," because
    of
    the "immediacy" of the government's interest in officer safety,
    not-
    withstanding its conclusion that "[e]ven a limited search of the
    outer
    clothing for weapons constitutes a severe . . . intrusion upon
    cherished
    personal security," 
    id. at 24-25.
    If an officer possesses a
    reasonable
    belief based on "specific and articulable facts" that the suspect
    is
    potentially dangerous, 
    id. at 21,
    reasoned the Court, then the
    officer
    is justified in undertaking the "limited steps" necessary to
    "protect
    himself and others from possible danger." Id . at 28.
    Fifteen years later, in Long, the Court authorized what are essen-
    tially "frisks" of automobile interiors during traffic stops, see
    Maryland v. Buie, 
    494 U.S. 325
    , 332 (1990), holding that such pro-
    tective searches are "justified by the principles. . . established
    in
    Terry." 
    Long, 463 U.S. at 1046
    . Recognizing that all "investigative
    5
    detentions involving suspects in vehicles are especially fraught
    with
    danger to police officers," 
    id. at 1047,
    and accepting without
    discus-
    sion that an area search of a vehicle is less intrusive than the
    frisk of
    the person, the Court concluded that "the balancing required by
    Terry
    clearly weighs in favor of allowing the police to conduct an area
    search of the passenger compartment to uncover weapons, as long as
    they possess [a] reasonable belief that the suspect is potentially
    dan-
    gerous." 
    Id. at 1051.2
    In Mimms and Maryland v. Wilson , 
    65 U.S.L.W. 4124
    (Feb. 19,
    1997), the Court even adopted bright-line rules that officers may,
    as
    a matter of course, order both drivers and passengers from vehicles
    during routine traffic stops in order to ensure that such stops are
    com-
    pleted without incident.
    The Court in Mimms held that the "inordinate risk" that exists
    every
    time "an officer . . . approaches a person seated in an
    
    automobile," 434 U.S. at 110
    , justifies a per se rule that drivers may be
    ordered out
    of their vehicles during lawful traffic stops, whether or not there
    exists any particular reason under the circumstances to believe
    that
    officer safety might be in jeopardy. In contrast to the substantial
    state
    interest in safety at stake when officers must approach a stopped
    vehi-
    cle, the Court characterized the additional intrusion on personal
    lib-
    _________________________________________________________________
    2 The Court expressly extendedTerry and Long in Buie, authorizing,
    "in conjunction with . . . in-home 
    arrest[s]," 494 U.S. at 337
    ,
    protective
    sweeps even of personal residences, where a reasonably prudent
    officer,
    based upon articulable facts, would believe "that the area to be
    swept
    harbors an individual posing a danger to those on the arrest
    scene." 
    Id. at 334
    (stating that the adopted standard "is no more and no less
    than was
    required in Terry and Long, and as in those cases, we think this
    balance
    is the proper one."). Although the Court remanded for application
    of this
    standard, it concluded that, even though the suspect sought by
    police had
    been arrested and handcuffed, and all discernible threat to the
    police had
    been neutralized, a "cursory search" of Buie's house still might be
    per-
    missible on the ground that the house could "harbor[ ] other
    persons who
    are dangerous and who could unexpectedly launch an attack" on the
    offi-
    cers. 
    Buie, 494 U.S. at 333
    . Not surprisingly, the Maryland Court
    of
    Appeals on remand did in fact hold that the cursory search of
    Buie's
    basement was reasonable. See Buie v. Maryland, 
    580 A.2d 167
    , 172
    (Md. 1990).
    6
    erty occasioned by requiring drivers to exit their vehicles and to
    move
    off onto the shoulder of the road as "de minimis," "at most a mere
    inconvenience," 
    id. at 111,
    and "hardly ris[ing] to the level of a
    ``petty
    indignity,'" 
    id. (quoting Terry,
    392 U.S. at 17), reasoning that
    "[t]he
    driver is being asked to expose to view very little more . . . than
    is
    already exposed" when the driver is seated in his automobile. 
    Id. Finally, repeating
    its oft-repeated observation that the government
    has a "legitimate" and "weighty" interest in officer safety, the
    Court
    in Wilson recently expanded the Mimms per se rule to allow officers
    to order not only drivers, but all occupants, to exit vehicles and
    move
    off onto the shoulder of the road during routine traffic stops. 
    See 65 U.S.L.W. at 4126
    . While acknowledging that the passengers' liberty
    interests implicated by orders to exit vehicles might be stronger
    than
    those of the drivers, the Court nonetheless readily concluded that
    these interests likewise are "minimal" and necessarily must yield
    to
    the state's interest in officer safety, finding persuasive
    Maryland's
    common-sense argument that every occupant in a vehicle "increases
    the possible sources of harm to the officer." 
    Id. A. 1.
    Notwithstanding that the Court "generally eschew[s] bright-line
    rules in the Fourth Amendment context," id . at 4125 n.1; see also
    
    Robinette, 117 S. Ct. at 421
    , we believe that the Court's decisions
    in
    Mimms and Wilson in particular would support a holding that when-
    ever, during a lawful traffic stop, officers are required to
    approach a
    vehicle with windows so heavily tinted that they are unable to view
    the interior of the stopped vehicle, they may, when it appears in
    their
    experienced judgment prudent to do so, open at least one of the
    vehi-
    cle's doors and, without crossing the plane of the vehicle,
    visually
    inspect its interior in order to ascertain whether the driver is
    armed,
    whether he has access to weapons, or whether there are other occu-
    pants of the vehicle who might pose a danger to the officers.
    Indeed,
    it seems to us that a contrary holding would not only be
    irreconcilable
    with, but arguably undermine altogether, the caselaw from the
    Supreme Court that was developed specifically for the purpose of
    pro-
    7
    tecting officer safety during what are, in today's society,
    frighteningly
    perilous encounters.
    Even where the interiors of vehicles are fully visible, "roadside
    encounters between police and suspects are especially hazardous,"
    
    Long, 463 U.S. at 1049
    , with as many as "30% of police shootings
    occur[ing] when a police officer approache[s] a suspect seated in
    an
    automobile," 
    Mimms, 434 U.S. at 110
    ; see also Adams v. Williams,
    
    407 U.S. 143
    , 148 n.3 (1972). In fact, as the Court noted recently
    in
    Wilson, in 1994 alone, 5,762 assaults on police officers occurred
    dur-
    ing the course of traffic pursuits or stops. See 
    Wilson, 65 U.S.L.W. at 4125
    (citation omitted). Thus, "it [is]``too plain for argument'"
    that
    the governmental interest in officer safety during traffic stops is
    sub-
    stantial. 
    Id. at 4125
    (quoting Mimms, 434 U.S at 110).
    When, during already dangerous traffic stops, officers must
    approach vehicles whose occupants and interiors are blocked from
    view by tinted windows, the potential harm to which the officers
    are
    exposed increases exponentially, to the point, we believe, of
    uncons-
    cionability. Indeed, we can conceive of almost nothing more danger-
    ous to a law enforcement officer in the context of a traffic stop
    than
    approaching an automobile whose passenger compartment is entirely
    hidden from the officer's view by darkly tinted windows. As the
    offi-
    cer exits his cruiser and proceeds toward the tinted-windowed
    vehicle,
    he has no way of knowing whether the vehicle's driver is fumbling
    for his driver's license or reaching for a gun; he does not know
    whether he is about to encounter a single law-abiding citizen or to
    be
    ambushed by a car-full of armed assailants. He literally does not
    even
    know whether a weapon has been trained on him from the moment
    the stop was initiated. As one officer put the obvious: "If the
    suspect
    has a weapon, I might not see it until he rolls down the window. He
    may just shoot me through the window."3 If, as the Court has
    noted,

    In contrast to the indisputably substantial government interest in
    protecting its law enforcement officials from the danger that
    inheres
    in the lawful stop of a vehicle with heavily tinted windows, the
    pri-
    vacy and liberty interests implicated by the opening of such a
    vehi-
    cle's door for the limited purpose of determining whether the
    vehicle
    is occupied by one or several persons and whether the vehicle's
    occu-
    pants are armed or have access to weapons, are, although not unim-
    portant, comparatively minor, and will always be so.
    It is axiomatic, of course, that "[o]ne has a lesser expectation of
    pri-
    vacy in a motor vehicle," in part because "its function is
    transporta-
    tion and it seldom serves as one's residence or as the repository
    of
    personal effects." United States v. Chadwick, 
    433 U.S. 1
    , 12 (1977)
    (quoting Cardwell v. Lewis, 
    417 U.S. 583
    , 590 (1974) (plurality
    opin-
    ion)). Because of this, and the fact that vehicular travel is, of
    neces-
    sity, highly regulated, individuals traveling in vehicles "must
    expect
    that the State, in enforcing its regulations, will intrude to some
    extent"
    on their privacy. New York v. Class, 
    475 U.S. 106
    , 113 (1986).
    But, apart from the fact that there is a considerably reduced
    privacy
    interest in a vehicle's interior passenger compartment as a matter
    of
    law, the driver and other occupants of a lawfully stopped vehicle
    have
    already had their liberty curtailed. Moreover, because the driver
    must
    comply with routine requests for identification and registration,
    he
    will be required at some point during the brief detention to expose
    the
    interior compartment of his vehicle to view through at least one
    win-
    dow, if for no other reason than to interact with the officer. Of
    course,
    when the driver lowers the window, then much if not all of the
    car's
    interior will be visible to the officer. The additional
    interference with
    the occupants' privacy interests affected by the opening of one of
    the
    vehicle's doors would seem minimal when measured against the enor-
    mous danger law enforcement officers face when they approach a
    vehicle with heavily tinted windows. Such an intrusion would seem
    considerably less than the intrusions affected by ordering the
    driver
    and passengers to exit the vehicle and to proceed to the shoulder
    of
    the road, which were held in Mimms and Wilson, respectively, to be
    "de minimis" in comparison to the states' interests in protecting
    their
    law enforcement personnel under circumstances far less inherently
    dangerous than those existing when the stopped vehicle has heavily
    tinted windows. Not only does the person subjected to the limited
    10
    search entailed in the opening of the vehicle door not have his
    entire
    body exposed to the view of the officers and public, he also
    retains
    his liberty interest in remaining seated in his automobile during
    the
    duration of the detention. Indeed, the actual invasion of privacy
    entailed in an officer's opening of the vehicle door is
    indistinguish-
    able from, if not precisely the same as, that which occurs when an
    occupant is required to open a door to exit a vehicle pursuant to
    an
    order given under the authority of Mimms or Wilson.
    2.
    Even if there were reasonable alternatives to allowing officers to
    open the door of a vehicle with heavily tinted windows in order to
    ascertain whether the driver is armed and whether there are other
    occupants in the vehicle, we would hesitate to impose them on the
    law enforcement community as a matter of constitutional law. As the
    Supreme Court has been at pains to observe, during Terry-type
    stops,
    officers "must make . . . ``quick decision[s] as to how to protect
    [them-
    selves] and others from possible danger'" at times when they are
    "par-
    ticularly vulnerable," and thus it has "not required that officers
    adopt
    alternate means to ensure their safety in order to avoid the
    intrusion
    involved in [such an] encounter." Long , 463 U.S. at 1052 (quoting
    
    Terry, 392 U.S. at 28
    ); see also 
    id. at 1052
    n.16. That is, the
    Court
    has scrupulously avoided substituting its judgment for that of law
    enforcement as to how best to ensure officer safety.
    With that said, however, we are at a loss to identify an acceptable
    alternative to a rule such as that we suggest would be justified.
    Upon
    a moment's reflection, it becomes apparent that neither requiring
    offi-
    cers (while in their cruisers or as they proceed toward the stopped
    vehicle) instead to order occupants to exit the vehicle nor
    requiring
    that they order that all of the vehicle's doors be opened,
    represents an
    acceptable, or even a reasonable, alternative. To require officers
    to
    order the vehicle's occupants to exit as the officers approach the
    stopped vehicle exposes the officers to the very danger to which we
    believe it is unconscionable to subject them, namely, that they
    might
    be fired upon as they approach the vehicle. As the Court observed
    in
    Terry, it is by definition "unreasonable to require that police
    officers
    take unnecessary risks in the performance of their 
    duties." 392 U.S. at 23
    . On the other hand, to insist that officers remain in their
    vehicles
    11
    and order the occupants out ignores the fact that, with heavily
    tinted
    windows, the officers could never know whether all of the vehicle's
    occupants had exited; and, eventually, the officers would still be
    required under this alternative to approach a vehicle which,
    insofar as
    the officers could know, still held passengers who might be armed
    and dangerous. Ordering that the vehicle's doors be opened, of
    course, allows the vehicle's occupants legitimately to move about
    the
    vehicle in ways that would enable them to access available weapons,
    which represents a separate danger unto itself.
    Therefore, in the end, we believe, it will be impractical, if not
    impossible, for law enforcement officers to neutralize the dangers
    to
    which they are exposed by virtue of heavily tinted windows. There
    simply do not appear to be any alternatives to the bright-line rule
    we
    suggest, which would infringe less on the residual privacy
    interests
    that drivers and passengers retain in the interior compartment of
    a
    lawfully stopped vehicle, yet still allow law enforcement officers
    to
    take that control of the situation that enables them to minimize
    the
    risk of harm to themselves and to the vehicle's occupants. Cf.
    
    Wilson, 65 U.S.L.W. at 4126
    ("The risk of harm to both the police and the
    occupants is minimized if the officers routinely exercise
    unquestioned
    command of the situation." (quoting Michigan v. Summers, 
    452 U.S. 692
    , 703 (1981)). A bright-line rule that officers could always
    pursue
    the course of opening the door of a tinted-windowed vehicle when,
    in their informed judgment, such an act appears necessary to
    protect
    their safety, would not render the stops of such vehicles
    risk-free, but
    it would at least reduce to an extent the enormous danger to which
    law enforcement authorities are exposed as a consequence of the
    advent of tinted windows.
    B.
    Even absent a Mimms/Wilson-type per se rule that officers may, in
    the circumstances we have described, open a vehicle's door to
    deter-
    mine the number of occupants within and whether any of those occu-
    pants are armed or have access to weapons, however, Officer
    Mackel's opening of Stanfield's passenger door was fully authorized
    under the principles, if not by the direct holdings, of Terry, Long
    and
    Buie. Officer Mackel's belief that he was potentially in danger as
    he
    approached Stanfield's Pathfinder was imminently reasonable; it
    12
    would be folly to suggest otherwise. Under Terry , Long and Buie,
    therefore, it is clear that Officer Mackel could have conducted a
    pro-
    tective search of the entire interior compartment of Stanfield's
    vehicle
    to ensure his safety and that of his partners. It follows a
    fortiori that
    Officer Mackel's much more limited search of merely opening the
    Pathfinder's door was reasonable under the Fourth Amendment.
    As our previous discussion suggests, we are convinced that the
    presence of windows so tinted that the vehicle's interior
    compartment
    is not visible is, in itself, a circumstance that would cause an
    officer
    reasonably to believe that his safety might be in danger -- as the
    dis-
    trict court held. When the fact of the tinted windows on
    Stanfield's
    Pathfinder is considered together with the other circumstances
    informing Officer Mackel's judgment as he approached Stanfield's
    vehicle on the morning of April 29, 1996, we are satisfied that no
    rea-
    sonable officer would have failed to appreciate the potential
    danger
    confronting Officer Mackel and his partners.
    First, Stanfield was, at the time of the stop, in violation of the
    state's traffic laws, having parked his Pathfinder in the middle of
    a
    two-way street, which was not passable by two cars simultaneously.
    See 
    Stanfield, 906 F. Supp. at 301
    . Second, Stanfield's vehicle was
    stopped in the early morning in a relatively deserted area of town.
    See
    id.; J.A. at 128. Third, Stanfield's vehicle was stopped in an area
    of
    Baltimore known for its open narcotics trafficking and high crime
    rate. See 
    Stanfield, 906 F. Supp. at 301
    ; J.A. at 53. As we have
    often
    noted, where there are drugs, there are almost always guns. And, as
    the Supreme Court has recognized, in a high crime area, "the
    possibil-
    ity that any given individual is armed is significant." 
    Buie, 494 U.S. at 334
    n.2. Fourth, Stanfield was driving a vehicle which,
    according
    to the officers' testimony and the district court's factual
    finding, "is
    of the class of four wheel drive vehicles favored by drug dealers,"
    and
    is also "the preferred target of car thieves." Stanfield, 906 F.
    Supp. at
    301 & n.3; J.A. at 163-64. Fifth, as the district court found, the
    offi-
    cers did not know and could not determine, because of the tinting
    on
    the windows, "whether Stanfield was alone or whether any weapon
    was within arms reach of the defendant." See Stanfield, 906 F.
    Supp.
    at 303. And, sixth, as the district court found, Stanfield had been
    seen
    by the officers conversing with William Staten, a known drug
    dealer,
    immediately prior to his encounter with Officers Mackel, Buie and
    13
    Hamel. 
    Id. at 301,

    to Defendant's Motion to Suppress Evidence). 5 Only the most fool-

    _________________________________________________________________
    5 Although the government opposed Stanfield's suppression motion,
    see Government's Memorandum of Law in Response to Defendant's
    Motion to Suppress Evidence, J.A. at 18-40, on appeal it
    inexplicably
    conceded error and then went to quite unusual lengths to have the
    case
    decided on the briefs and without oral argument. Unwilling to
    reverse the
    district court's judgment summarily, we ordered the reluctant
    Assistant
    United States Attorney, Philip S. Jackson, to appear and argue the
    case.
    When confronted by the court with the Supreme Court authorities
    described above, and questioned why he was unable even to advance
    good-faith arguments before this court in support of the district
    court's
    judgment, Mr. Jackson represented to the court that he had
    confessed
    error solely because, in his view, there was no basis for the
    district
    court's finding that Staten was a known drug dealer, a view that
    was
    nowhere mentioned in the government's three and one-half page
    brief.
    Mr. Jackson thereafter, however, conceded that neither he nor the
    United
    States had any basis at all for challenging the district court's
    finding as
    clearly erroneous, ultimately acknowledging that if that finding
    were sus-
    tained, the United States had improperly confessed constitutional
    error.
    We find the district court's finding to be amply supported by the
    record, especially the testimony of Officer Mackel, in response to
    ques-
    tions from Stanfield's counsel:
    Q: What really happened here was that you were on routine
    patrol, in your bullet proof vests, and you saw Mr. Stanfield
    talk-
    ing to someone who you knew, isn't that correct?
    A: Once I pulled into the block, that is correct. I recognized
    who it was.
    . . .
    Q: . . . Now, when you saw Mr. Stanfield talking to someone,
    isn't it true that that is why you really stopped your vehicle
    and
    got out of the car and started investigating Mr. Stanfield?
    A: No.
    Q: Isn't it true that that person [Staten] you had known
    through
    previous, I guess through some previous dealings, that he
    might
    be or was a law breaker?
    A: Yes, I had dealings with Mr. Staten before.
    14
    Q: And the real reason you got out of the car, all three of
    you,
    had nothing to do with being double parked, but you wanted to
    see what was up, isn't that correct?
    A: No, that is not true.
    Q: And you really, all you really had was a hunch and you just
    wanted to go in and see what was up?
    J.A. at 152.
    It is plain from this exchange between defendant's own counsel and
    Officer Mackel that defense counsel himself understood that Officer
    Mackel had previously had "dealings" with Staten in connection with
    drug transactions. Stanfield even contended to the district court
    that, as
    the officers exited their cruiser, "one of the officers then
    shouted up to
    William [Staten] and asked [Staten] whether he had stopped dealing
    drugs." See J.A. at 238.
    It is plain that defense counsel's strategy was to develop a case
    that the
    officers had relied upon the pretext of Stanfield's traffic offense
    to inves-
    tigate their "hunch" that, because Stanfield was talking to a known
    drug
    dealer, he might be engaged in a drug transaction, and, in fact,
    this was
    the very argument defendant advanced before the district court, see
    J.A.
    at 238 (opinion of district court) ("Stanfield argues that the
    officers were
    not attracted to him because of any traffic violation but because
    they
    were investigating drug trafficking."). Indeed, although Stanfield
    (for
    obvious reasons) does not mention the officers' previous dealings
    with
    Staten in his submissions to this court, one of Stanfield's two
    assign-
    ments of error from the district court's denial of his suppression
    motion
    was that the officers acted only on this hunch. See Appellant's Br.
    at 2-
    9.
    It is evident, therefore, that the district court's finding that
    Stanfield
    was talking with a man known by the officers to be a drug dealer is
    unas-
    sailable. The Assistant United States Attorney himself, albeit in
    direct
    contradiction of his own representations before us, even
    represented to
    the district court that "[a]n officer recognized th[e] individual
    [to whom
    Stanfield was talking] as William Staten, an individual about whom
    [the
    officer] had received information indicating Staten's involvement
    in the
    distribution of controlled substances." See            Government's
    Memorandum
    of Law in Response to Defendant's Motion to Suppress Evidence, J.A.
    at 18, 19.
    15
    hardy would not have believed that his safety was"potentially" in
    danger, see 
    Long, 463 U.S. at 1051
    , as he approached Stanfield's
    Pathfinder.
    There was more reason for Officer Mackel to believe that his safety
    might be in danger than there was in Long for Deputies Howell and
    Lewis to believe that their safety might be in danger. The Supreme
    Court there held that Howell and Lewis were "clearly justified" in
    their conclusion that Long might pose a danger to them were he
    allowed to reenter his vehicle because (1) "[t]he hour was late and
    the
    area rural," (2) Long had been speeding and had swerved into a
    ditch,
    (3) Long had appeared to be under the influence of an intoxicant,
    and
    (4) the officers had seen a hunting knife on the floorboard of
    Long's
    
    car.6 463 U.S. at 1050
    . The Court readily reached this conclusion
    not-
    withstanding that the officers had already completed their
    detention
    of the suspect without incident; they knew that there were no other
    occupants in Long's vehicle; they also knew that there was no one
    else in the vicinity who could pose an immediate threat to their
    safety;
    _________________________________________________________________
    6 When listing the circumstances supporting the reasonableness of
    the
    officers' belief that they might be in danger if Long were allowed
    to
    reenter his vehicle, the Court did, as noted, mention that the
    officers had
    earlier seen the hunting knife on the floorboard of Long's
    automobile. It
    is relatively clear, however, that the knife was mentioned more in
    sup-
    port of the court's alternative holding that the search of Long's
    person
    was also reasonable, and that the presence of the knife played
    little, if
    any, role in the Court's determination that Officers Howell and
    Lewis
    were reasonable in their belief that their safety might be at risk
    if Long
    were allowed to reenter his car, 
    see 463 U.S. at 1050
    & n.15. When
    it
    mentioned the knife, the Court even noted that " Long was not
    frisked
    until the officers observed that there was a large knife in the
    interior of
    the car into which Long was about to reenter," 
    id. at 1050
    (emphasis
    added), and, as the Court had noted earlier, after observing the
    knife on
    the floorboard, "[t]he officers [had] stopped Long's progress and
    sub-
    jected him to a Terry protective pat-down." 
    Id. at 1036.
    As the
    Court
    explained, the question with respect to the search of the vehicle's
    passen-
    ger compartment was whether the officers acted "unreasonably in
    taking
    preventive measures to ensure that there were no other weapons
    [other
    than the knife] within Long's immediate grasp before permitting him
    to
    reenter his automobile." 
    Id. at 1051
    (emphasis added).
    16
    they knew that Long did not have a weapon on his person; they had
    determined that, although Long was not impaired sufficiently that
    he
    could not drive, he was unlikely to initiate an assault on the
    officers;
    and they had reason to believe that Long wished to leave the scene
    without further involvement with the authorities.
    In contrast, here, Officers Mackel, Buie and Hamel had just initi-
    ated their encounter with Stanfield, who was driving a vehicle not
    uncommonly associated with drug activity; they were in a high crime
    area known for its open drug trafficking; they had, only moments
    ear-
    lier, seen Stanfield talking with a known drug dealer; they did not
    know whether Stanfield was alone or accompanied by others; they
    were unable, because of the tinting of the windows, to determine
    whether Stanfield, or any other occupants of the vehicle, were
    pres-
    ently armed or had ready access to weapons; and they had no reason
    to think Stanfield might be incapacitated in such a way as actually
    to
    reduce any threat he might pose to them.
    If there was less reason for Officer Mackel to believe that he
    might
    be in danger than there was in Terry for Officer McFadden to
    believe
    he might be in danger, we are satisfied that the difference is not
    sig-
    nificant enough to warrant a different conclusion as to the
    reasonable-
    ness of Officer Mackel's perception of possible danger, especially
    given the greater vulnerability of the officers here because of the
    heavy tinting of the Pathfinder's windows. Officer McFadden had
    observed conduct by Matthew Terry and his companions that was
    entirely innocent in itself, although suspicious to McFadden, a
    trained
    officer, who recognized the conduct as "consistent with [an]
    hypothe-
    sis that the[ ] men were contemplating a daylight robbery." Terry,
    392
    U.S at 28. Under these circumstances, observed the Court, it was
    rea-
    sonable for Officer McFadden to assume that one or more of the men
    might be armed. Here, of course, Stanfield was not engaged in
    entirely innocent behavior; he was actually committing an offense,
    albeit a relatively minor traffic offense, when he was stopped.
    And,
    it bears repeating, he was stopped in an area of the city known for
    its
    open drug trafficking, in a vehicle frequently associated with drug
    activity, and he was talking with a known drug dealer. A trained
    offi-
    cer certainly would be as warranted in believing that his safety
    might
    be in danger in these circumstances as in those present in Terry.
    Of
    course, in neither instance need the officer have been "absolutely
    cer-
    17
    tain that the individual [was] armed; the[only question] is whether
    a
    reasonably prudent man in the circumstances would[have been] war-
    ranted in the belief that his safety or that of others was in
    danger."
    
    Terry, 392 U.S. at 27
    . As to this question, in this case, we have
    no
    doubt whatsoever.
    Although the Court in Buie did not itself resolve the ultimate
    issue
    of whether the protective sweep undertaken by the officers was
    justi-
    fied under the Terry and Long standard, which the Court there held
    was applicable to the officers' sweep of Buie's home, the Court
    spe-
    cifically analogized law enforcement's interest"in taking steps to
    assure themselves that the house in which a suspect is being, or
    has
    just been, arrested is not harboring other persons who are
    dangerous
    and who could unexpectedly launch an attack," to the "immediate
    interest of the police officers [in Terry and Long] in taking steps
    to
    assure themselves that the persons with whom they were dealing were
    not armed with, or able to gain immediate control of, a weapon that
    could unexpectedly and fatally be used against them." 
    Buie, 494 U.S. at 333
    . The Court noted that an in-home arrest, unlike the typical
    encounter on the street, "puts the officer at the disadvantage of
    being
    on his adversary's ``turf[,]' [and that] [a]n ambush in a confined
    set-
    ting of unknown configuration is more to be feared than it is in
    open,
    more familiar surroundings." 
    Id. Even so,
    however, the Court was
    hesitant to characterize either the risk of danger during an
    in-home
    arrest or the risk of danger in an "on-the-street or roadside
    investiga-
    tory encounter" as the greater. 
    Id. Based upon
    these overarching
    observations concerning the relative risks associated with in-home
    arrests and traffic stops, and with due regard to the relevant
    specifics,
    we are even unprepared to say that the risk of danger to Officers
    Mackel, Buie, and Hamel was less pronounced than was the risk to
    the officers in Buie.
    First, and most significantly, any difference between the inherent
    risk existing during an in-home arrest and a lawful investigatory
    traf-
    fic stop due to the officers' lack of familiarity with the
    surroundings,
    was minimized, if not entirely eliminated, in this case, because
    the
    interior of Stanfield's vehicle was not visible to the officers.
    Through
    the use of heavy tinting, the driver and occupants of a vehicle
    effec-
    tively secure for themselves, as Stanfield did in this case, a
    "confined
    setting of unknown configuration," forcing law enforcement authori-
    18
    ties to confront them on their own "turf"-- not unlike if they were
    hiding in their home. Second, some six or seven officers were
    present
    at Buie's residence to affect the arrest, whereas only three
    officers,
    were investigating Stanfield. Third, the officers in Buie had
    proceeded
    to Buie's house for the specific purpose of arresting Buie and were
    fully prepared for anything that might develop in connection with
    that
    assignment; unlike Officers Mackel, Buie, and Hamel, they had not
    simply come upon Buie unexpectedly in circumstances requiring a
    quick, on-the-street judgment. Fourth, the officers had already
    arrested Buie and had only to depart the residence and premises; at
    the time of their search of Buie's basement, the officers were not
    merely beginning their investigatory detention, as in the case sub
    judice, when a confrontation is more likely. Fifth, two days had
    lapsed since the robbery in Buie, and, although it was certainly
    not
    unreasonable to think someone (in particular, Buie's accomplice)
    might be hiding in the house with Buie, the officers had nothing
    spe-
    cific to support such an inference. As the dissenting judge on the
    Maryland Court of Appeals said in his opinion on the remand from
    the Supreme Court:
    From the information elicited at the suppression hearing, we
    do not know whether Allen [Buie's accomplice] had been
    arrested or was still at large. The testimony at the hearing
    does not give any indication that Allen was seen entering or
    leaving Buie's home during the three day surveillance
    period. In fact, there was no testimony that placed Allen at
    Buie's home at any time prior to Buie's arrest. Neither is
    there information as to what type of relationship Buie and
    Allen had; that is, we do not know whether they were long-
    time friends who spent a great deal of time together or
    whether the only time they were ever together was the night
    of the alleged robbery.
    The inconclusive surveillance . . . does not help the State.
    It surely does not permit the inference that the police
    thought Allen was at Buie's house, for if they had believed
    that they would have brought along his arrest warrant as
    well as Buie's.
    Buie v. Maryland, 
    580 A.2d 167
    , 173-74 (Md. 1990) (Adkins, J., dis-
    senting). Here, of course, while Officers Mackel, Buie, and Hamel
    19
    likewise had no specific reason to believe that there were other
    pas-
    sengers in the Pathfinder, they did know that there was someone in
    the vehicle (Stanfield) who, for the reasons earlier recited,
    potentially
    might be dangerous.
    In contrast to the substantial state interest in having the
    investiga-
    tory detention necessitated by Stanfield's traffic infraction
    conclude
    without harm to its law enforcement officials, the liberty and
    privacy
    interests which Stanfield attempts to protect are, for the reasons
    previ-
    ously discussed, notably insubstantial. Additionally, because, even
    according to Stanfield, the driver's side window was down when the
    officers approached the Pathfinder, the interior of Stanfield's
    car, as
    well as contents lying exposed on the back seat, were fully open to
    the view of the officers and passersby.7 Even had all of the
    Pathfind-
    er's windows been raised, the undisputed evidence in the record
    before us is that Stanfield's tinted windows would not have
    prevented
    passersby from viewing the Pathfinder's interior under all lighting
    conditions. See J.A. at 88. Hence, it was only because of the mere
    happenstance of cloud cover that the back seat of Stanfield's car
    was
    not visible, just as in Texas v. Brown , 
    460 U.S. 730
    (1983), the
    inte-
    rior of the open glove compartment was not visible to the officer
    only
    because of the happenstance that the stop occurred at night. There-
    fore, as the district court alternatively held, it is questionable
    whether
    Stanfield had any privacy right at all in those portions of his
    interior
    passenger compartment relevant in this case, for there is no
    legitimate
    expectation of privacy "shielding that portion of the interior of
    an
    automobile which may be viewed from outside the vehicle by either
    inquisitive passersby or diligent police officers." 
    Id. at 740.

    7 This fact, of course, suggests that the district court's denial
    of Stan-
    field's suppression motion might well be sustainable on the
    alternative
    ground that the cocaine would inevitably have been discovered by
    Offi-
    cer Buie or Officer Hamel, even had it not been discovered by
    Officer
    Mackel. Where the preponderance of evidence establishes that the
    infor-
    mation would "ultimately or inevitably" have"been discovered by
    means
    wholly independent of any constitutional violation," the inevitable
    dis-
    covery exception to the exclusionary rule allows the prosecution to
    admit
    the evidence obtained through an illegal search. Nix v. Williams,
    
    467 U.S. 431
    , 443 (1984).
    20
    Assuming that Stanfield did have some residual privacy interest in
    the interior compartment of his car, the additional intrusion on
    that
    interest that resulted from the mere opening of the passenger door
    was
    inconsequential. There is, of course, no comparison between the
    "se-
    vere," "surely . . . annoying, frightening, and perhaps
    humiliating"
    pat-down of the person authorized by the Court in 
    Terry, 392 U.S. at 24-25
    , and the incremental additional intrusion on Stanfield's
    privacy
    interests affected by the mere opening of his passenger door. Simi-
    larly, the protective sweep of the home authorized by the Court in
    Buie, pursuant to which the police were authorized to search
    closets,
    showers, attics, studies, basements, and underneath beds, was much
    more offensive to privacy interests than was the search here. And,
    obviously, the opening of the car door and perusal of the car's
    interior
    from the outside interfered less with Stanfield's privacy interest
    than
    would have a complete search of the vehicle's interior permitted
    under Long, which could have included visual inspection of any area
    in which a weapon might have been secreted.
    We even believe, as 
    explained supra
    , that the intrusion affected by
    Officer Mackel's mere opening of the passenger door of Stanfield's
    Pathfinder was considerably less than those intrusions authorized
    as
    a matter of course by the Court in Mimms and Wilson. The opening
    of the door of the Pathfinder exposed to view little more of
    Stanfield's
    body than was already exposed to view through the open driver side
    window and little more of the interior compartment than was visible
    through that same window. And, in contrast to the action that may
    be
    ordered under Mimms and Wilson, the mere opening of the door did
    not require Stanfield (nor would it have required any other
    occupants
    of the vehicle) to move at all.
    In sum, when the state's substantial interest in ensuring that its
    investigatory detention of Stanfield occurred without incident to
    its
    law enforcement agents is weighed in the balance with Stanfield's
    pri-
    vacy interests implicated by Officer Mackel's search, there can be
    no
    doubt but that the search was reasonable under the circumstances
    and
    appropriately limited in scope. What was said of Officer McFadden's
    actions in Terry is no less true of Officer Mackel's actions here:
    We cannot say his decision [to open the passenger door to
    Stanfield's Pathfinder in order to determine whether there
    21
    were other passengers in the vehicle or whether the driver
    or other had access to weapons] was the product of a vola-
    tile or inventive imagination, or was undertaken simply as
    an act of harassment; the record evidences the tempered act
    of a policeman who in the course of an investigation had to
    make a quick decision as to how to protect himself and oth-
    ers from possible danger, and took limited steps to do 
    so. 392 U.S. at 28
    . To hold otherwise than we do today would be "to
    require that police officers take unnecessary risks in the
    performance
    of their duties," 
    Terry, 392 U.S. at 23
    , something which, as the
    Supreme Court has consistently held, the Constitution does not
    require.8
    III.
    Because Officer Mackel was engaged in a reasonable protective
    search when he opened Stanfield's passenger door for the limited
    pur-
    pose of determining whether Stanfield was armed and whether there
    were any other occupants within the vehicle who might pose a danger
    to him or his partners, and because the cocaine that Stanfield
    seeks
    to suppress was seen by Officer Mackel in plain view during the
    con-
    duct of this reasonable search, the district court's denial of
    Stanfield's
    motion to suppress is affirmed.
    AFFIRMED
    _________________________________________________________________
    8 Stanfield also argues that the initial seizure of his vehicle was
    illegal
    because the officers stopped his vehicle in order to investigate
    possible
    drug trafficking, not, as the officers contended, because he was in
    viola-
    tion of the state's traffic laws. See supra note 5. Because, as
    the Supreme
    Court has recently held, an officer's subjective state of mind in
    stopping
    a vehicle is irrelevant to the constitutionality of the stop, see
    
    Robinette, 117 S. Ct. at 420
    ("``Subjective intentions play no role in
    ordinary,
    probable-cause Fourth Amendment analysis.'" (quoting Scott v.
    United
    States, 
    436 U.S. 128
    , 138 (1978)); Whren , 116 S. Ct. at 1774
    ("[Our]
    cases foreclose any argument that the constitutional reasonableness
    of a
    traffic stop depends on the actual motivations of the individual
    officers
    involved."), the district court was unquestionably correct in
    rejecting this
    argument.
